BLIND-STITCHING SElVING-MACHINE.

To all whom it may concern;

Be it known that we, CHARLES SCUDDER and FRANK CORYELL, citizens of theUnited States of America, and residents of Trenton, in the county ofMercer and State of New Jersey, have invented certain new and usefulImprovements in Blind-Stitching Sewing-Machines, of which the followingis a specification.

A difficulty heretofore experienced with blind stitching sewing machineshas been that they could not finish certain classes of Work, such as thebottoms and lapels of coats etc., but only circular work, such astrousers legs, skirt bottoms etc. The reason for this defect lies in thefact that with these machines the feed is at a point more or lessdistant from the needle, thus, unless the work is of a circularcharacter, always leaving unsewed that portion of the material betweenthe points where it is grasped by the feed and engaged by the needle.The result has been to greatly limit the field of usefulness of blindstitching machines; such work as they were unfitted to properly do beingstill done by hand. Another disadvantage found with former blindstitching machines has been that, in sewing goods of a close or toughtexture, they are not sufficiently held by the presser foot, and as thepoint of the needle touches the fabric the fabric stretches or movessufficiently to divert the course of the needle, throwing it against theshuttle, or the needle may pass entirely through all the goods and notmake a blind stitch. To overcome this moving of the goods, the ordinaryractice has been for the operator to hold t ie unsewed end with a manualtension. This tension to be effectual must be uniform, for if it is toogreat, the thickness of the goods against the cloth roller at thestitching point will be reduced and the needle will not take hold of thegoods at all. or not suffi,- ciently to make a blind stitch, the undercloth being stretched and compressed to such a thinness that the needlewill not touch it. If the tension is too little, then the goods willmove, with the results as above stated. It is a physical impossibilityfor the operator to pull with the same tension upon the cloth at alltimes, and even if this could be accomplished by the resser footuniformly upon all kinds of fabrics, the distance between the presserfoot and the stitching point would permit of a stretching of the goodswhich would decrease the prob- Specification of Letters Patent.

l ability of a perfect stitch. The difficulties just enumerated in thisclass of machines result from the cloth not being properly held at thestitching point while the stitch is being made.

The main object of our invention is to overcome the above named seriousdefects in blind stitching sewing machines. le have also, in carryingout the main ideas, added many minor improvements with the object ofproducing a machine at once easily accessible, quickly adjustable andconvenient of operation.

In general terms, the organization comprising the invention consists ofa work carrier having a working surf ace for the cloth to be sewed, afeeding mechanism for said cloth consisting of two enacting elements,and a reciprocating needle whose path lies between said elements, thesaid mechanism being adapted to feed the cloth from its path on saidsurface to a position below said surface.

More specifically, the improved machine consists of a feed roller whoseaxis is horizontal and which is adapted to feed the material to beworked upon in a vertical direction, a cloth roller parallel to andcontiguous to the feed roller and lying approximately in the samehorizontal plane and around which the said material may fold and passbetween said rollers, a vertically reciprocating vertical needle whoseath lies between said rollers, said feed ro ler having an yannularportion cut away in the path of said needle, a shaft upon which saidfeed roller is secured, a slide having bearings for and carrying saidshaft, said feed roller and slide being yieldable in a horizontaldirection away from said cloth roller, said slide having a check 'forlimiting its movement in each direction, a spring pressing said slideand feed roller towards said cloth roller, means for adjusting thetension of said spring, a clutch on said shaft, a lever extendingdowiiward from said clutch, a driving mechanism, a substantiallyhorizontal link connecting said lever with said mechanism, saidmechanism consisting of a compound lever, a bed plate for the machine,said bed plate having guiding surfaces for receiving and guiding saidslide, a retaining clip for said slide attached to said bed plate, athumb piece secured to the top of said slide, said means, consisting ofa thumb screw, a bearing for said thumb screw attached to said bedplate, and a traveling nut on said thumb screw and engaging said spring,a cloth plate to one edge of which said cloth roller is attached, ahorizontally swinging work carrier fulcrumed on said bed plate, saidcloth plate being mounted on said work carrier and adjustable thereon toand from said needle, a vertical pivot for said work carrier, a stop forlimiting the inward movement of said carrier, a latch l'or locking saidcarrier in operative position, said work carrier having a transverseundercut depression on its upper surface, said cloth plate being seatedand guided in said depression and the upper surface of said plate beingY[lush with the upper surface of said work cz'irrier, said carrierhaving a transverse slot there through and said cloth plate having anopening therethrough registering with said slot, a screw lixedtransversely in said carrier and traversin(r said slot, a thumb nutmovable on said screw in said slot and engaging said cloth plate at saidopening, said feed roller having annular grooves therein, cloth-guidingfingers lying in said grooves and extending downwardly and outwardly,said fingers being carried by said slide, said slide having a depressedseat in its upper surface and adjoining said feed roller, a platesecured in said seat, the upper ends ot said lingers being attached tosaid plate, and a presser foot above said cloth roller and adapted topress said material down thereupon.

The invention will now be described in detail with reference to theaccompanying drawings Figure 1 is an elevation of that portion of themachine above the bed plate, and a vertical section of the bed plate onthe lines V-V of Figs. el and 6, the work carrier being removed to givea clear view of the feed roller, and the mechanism beneath the bed platebeing shown in elevation. Fig. 2 is an elevation ot the machine from thelel't of Fig. 1, the work carrier being in ilace, and shows the relationof the feed rol er and cloth roller to each other and to the needle.Fig. 3, is section on the lines lil- WY of Figs. 1, 4 and 7, Figs. 1 and4 being viewed from the lel't, and Fig. 7 from the right. This ligureshows the clutch for operating the Jfeed roller and t ie mechanism bywhich the same is driven.

Fig. 1G ispartial section` on the lines ZWZ ol' Figs. t' and 1t).

The main driving shaft of the machine the horizontal shalt 1, and 2 isthe vertical auxiliary shaft. The needle 3 is carried by the usualneedle bar 4 which is supported in the head 5 and connected up in theusual way with the horizontal shalt 1 for reciprocating the needle in avertical direction. So lar as our invention is concerned, the needle mayor may not have a lateral throw for producing a zig zag stitch, but itis usual, on account ol' the requirements of the work, lor the needlesoll blind stitching machines to have such lateral throw, and the machineto which our invention is shown as applied is of that type. The lateralthrow is given lo the needle bar 4 by the pitman 6 and rocking lever 7,one end of said lever being connected up to said needle bar within thehead 5, and the said. rock lever being operatively connected to theshaft l, the am litude olI the throw being varied by adjusting the otherend of the said pitman to various positions on the said rock lever bymeans of the thumb screw S. The presser foot t) is carried upon then'esser i'oot bar 1() which is supported in the iead 5 in the usual way.

There is nothing new about the mechanism ot the presser foot and needle,but they are correlated in a direct way to certain pai s ol' ourinvention, therefore they are described. Other parts of the generalorganization olI the machine, not so correlated, are not described.

11 is the main bed plate of the machine to the top side oiE which ispivoted the horizontally swinging work carrier 12 by the verticalcounter-sunk screw bolt 13 which serves as a pivot and which has the jamnut 14. The bed plate 1] does not extend under the work carrier 12except at the pivoted end ol said work carrier. The work carrier 12 hasa straight workiiig edge extending l'or some distance both ways from theneedle 3 and adjacent to said working edge has a sloping portion 12, toallow room for the folding of the cloth thereover. The said work carrier12 is provided with a transverse depression 15 having under cut edges1.6 and in which slides the cloth plate 17, and on the front edge ofsaid cloth plate is a cylindrical cloth roller 18 carried by bearings1.9 attached to the under side of said plate, The cloth` plate 17 has anopening 2() therethrough registering with the transverse slot 21 throughthe work carrier 12` and a screw 22 is fixed transversely in said workcarrier and. traversing said slot, and a thumb nut 2S adapted to travelin said slot on said screw engages the cloth plate 17 at the saidopening, for adjusting said cloth plate transversely of said workcarrier, and toward or from said needle. A pin 24 set in the bed plate11 engages the projection 25 on the work carrier 12 and limits theinward movement of said carrier, while the latch 26, having a handle 27and secured to the bed plate 11 by the screw 28, locks said carrier inoperative position. A pin 29 in the edge of the bed platc1 1 preventsthe latch 26 from swinging too far upward when the same is released.

The cam 30 on the vertical shaft 2 engages one end of the lever 31, andthereby manipulates the mechanism for operating the feed roller 312.rllhe fulcrum of the lever 31 is at 33, and the fulcrum 33 is carried.by the bar 34 which slides in guides 35 forming a part of the hed plate11 and retained in place by the fastening 36 secured to said bed plateby screws 37, and a screw handle passes upward from bar 34 through aslot 39 in the bed plate 11. The fulcrum 33 may slide on the lever 31,and by adjusting the screw handle 38 to different positions along theslot 3Q, the fulcrum 33 is moved to correspondingly different positionson the lever 31, for varying the length of the feed. 'lhe lever 31 isprevented from moving in a longitudinal direction by a pin 4() carriedby the bed plate 11 and engaged in a slot 41 in said lever. The otherend of the lever S1 connected to one end of the lever b v the link 43and interposed distance-block 31, and the other end of the lever 42 isconnected to one end of the lever 44 by the link 45, and the levers 42and 44 respectively are supported and swiveled on studs 46 and 47attached to the under side of the bed plate 11. The other end of thelever 44 carries a swivel stud 4S, and a retractile spring 4,0 connectssaid stud with the link 43, for taking up all lost motion in the systemof levers during their idle stroke, thus enabling them to deliver acomplete working stroke. 'lhe levers 31, 42 and 44 are each of the firstclass, and the fulcrums of the levers 42 and 44 are in each case locatednearest to the end of the lever at which the power is applied, thusmultiplying the motion, so that the end of the lever 44 to which theswivel stud 48 is attached moves several times farther than the end ofthe lever 31 to which is connected the link 43, the purpose of this xmultiplied motion being to give a sufficient partialrevolution to thefeed roller 32 at each vibration of the said levers. The feed roller 32is fixed on a shaft 50 mounted in bearings 51 on the slide 52. A clutch53 is secured on the shaft 50, and an operating lever 54 cX- tendsdownward from said clutch and is connected at its lower end by thesubstantiallvI horizontal link 55 to the swivel stud 4S. The lever 54secured to the clutch member 56, which is loose on the shaft 50, therolls 57 forming an operative connection between the two parts of theclutch. There is nothing new about the mechanism of the clutch 53,therefore the details of its construction need not be further explained.Then the lever 54 is oscillated, through. its connection with the lever44 by the link 55 and swivel stud 4S, the clutch 53 is operated tointermittently rotate the shaft 50 and feed roller 32. A housing 58 isattached to the bed plate 11 and covers the clutch 53 and the pivotedend of the work carrier 12.

The bed plate 11 has a depressed )ortion 59 with guiding surfaces 6()within which is located the slide 52. The slide 52 is held in place bythe retaining clip 61, which is attached to the bed plate 11 of themachine. The slide 52 is free to move back and forth in a directiontoward or from the needle 3, but its movement is limited in eachdirection by the lug 62 thereon coming in contact with the bed. plate 11at each end of the slot 63 in said bed plate. The slide 52 has a recess64 on its under side, and within said recess is an expansivehelical'spring 65, said spring being retained in lace by the pin 66 andthe inner end of the tiumb screw 67, said spring abutting at one endagainst the slide 52 and at its other end against the traveling nut 6Bon the. screw 67, the said thumb screw 67 having a bearing 69 attachedto the side wall 7() of the bed plate 11 by screws 71, whereby when saidthumb .screw 67 is turned in one direction the spring 65 is compressedand when. it is turned in the opposite direction the tension of thespring 65 is released, the constant tendency of the spring 65 being toforce the feed roller 32 towards the cloth roller 18, the said feedroller and cloth roller lying in about the same horizontal plane. Theneedle 3 reciprocates in a vertical direction near the cloth roller 18on the side next to the feed roller 32, and the cloth roller 32 has aportion cut away at 72 to allow room 'for the vertically reciprocatingneedle if. to pass without striking, and said feed roller being thus cutaway for a width a little greater than the widest vlateral throw towhich said needle is subject. On the top side of the slide 52 is secureda thumb piece 73 by which the feed roller 32 may be manually pushed backaway from the cloth roller 18 against the tension of the spring 6.5, thesaid feed roller and shaft 5U heing carried straight back and alwaysremaining parallel to the cloth roller 18. 'lhe feed roller 32 may yieldagainst the tension of the spring 65 to permit the passage of seams, hutsuch yielding in no way interferes with the proper propulsion of thesaid 'feed roller, on account of the vertically disposed level' 54 andhorizontal connecting link 55 permitting a free lateral movement of theshaft 5() without interfering with the action of the clutch .53.

The feed roller 32 is provided with annular grooves 74, and the slide 52has on. its upper side a depressed portion 75 in which is seated andsecured the plate 76 having attached thereto the cloth-guiding iingers77, the said tingers 77 lying in said grooves 74 to a depth below thecorrugated surface of the feed roller 32 and on the upper and outersides of said feed roller and extending beyond said feed rollerdownwardly and outwardly at an angle of about -15 degrees, said vfingers77 heing for the purpose of guiding the material to he worked uponaround the cloth roller 1.8 and for directing :it away from the shuttle.mechanism 78. The fingers 77 are attached to the )late 76 hy beingsecured in grooves on the liottom side thereof.

'lf he shuttle mechanism 78 is readily accessihle hy swinging open thework carrier 12.

l`he presser foot t) is curved downwardly at 79 so that it is adapted tohold the material down upon the cloth roller 18 and at the salue time heclear of the feed roller 32, the said material passing heneath thepresser foot tl, folding around the cloth roller 1S and heing feddownwardly between the cloth roller 1S and the feed roller 32 and in thepath of the needle 3, the feed roller 32, hy reason ol the spring G5,pressing the said material against the cloth roller t8, and the needle2% piercing the said material at the same horizontal plane at which itis eng: .ged hy the feed roller 32.

To insert the work in our machine, thtI needle l should he at itshighest point and the presser foot 9 should he raised, then the feedroller 32 should he pushed hack hy means ol' the thumh piece 73 and thework slipped over the work carrier l2 and cloth roller 1N, or, if moreroom is desired, hy releasing the latch 26 the work carrier 12 may heswung open, the work placed in position around the cloth roller 1h', andthe work carrier l2 closed, when it will he automatically locked inoperative position hy the dropping olI the latch 2G, The depth ofthestitch is determined hy the distance of the cloth roller 1X from theneedle 3, and is regulated hy turning the thunih nut 23, which travelson the screw 22 and moves the cloth plate 17. As the work carrier 12 islocked in rigid position, and as the cloth plate 17 slides in thedepression 15,

the cloth roller 18, in any adjustment, always remains parallel to thefeed roller 32. The pressure of the feed roller 32 upon the` matcrialheing worked upon may he vregulated hy turning the thuinh screw G7. Thestitch is formed in a manner eonnnon to this class of machines, thematerial douhling over the cloth roller 18 and the needle Jl piercingthe salue at thc fold. ll" there is only one thickness of cloth, as inornamental stitching, and in overseaming, the cloth roller la isadjusted so that the needle 3 will pass just near enough to it to passpart way through the cloth and out again on the salue side thereol', andwhen there are two thicknesses of cloth, adjust.- ment is made so thatthe needle I passes through the outer layer of cloth and part waythrough the second layer and ont again through the lirst named layer,thus stitching the two thicknesses together, in hoth instances thethreads only showing on one side of the work, hecause the stitch onlygoes part way through the last thickness ol' cloth. The cloth roller 1Sserves the douhle purpose of 'forming a folding edge for the materialworked upon and as a hacking for the feed roller 532. By reason ofthel'ced roller 32 hcing located adjacent to the needle il, the niatcrialis grasped hy the said l'eed roller at the` saine point at which it isengaged hy the said needle, thus permitting the scam to hegin at theextreme end ol a piece ot' goods, and litting the machine for straightline work as well as circular seams. Also in our machine the goods insewing will he held not only hy the presser foot, hut also hy the feedand cloth rollers suhstantially at each side of the point where theneedle enters the goods, so that at all times during sewing the` clothis held lirluly at tht` stitching point. This enaliles the machine tohlind stitch goods of a close or tough textiire,which could nototherwise he done. The operator need only guide the goods in sewing.

The upper surface of the cloth support or work-carrier12, and ol' thecloth plate 17 forming a part thereof, act as a guide for keeping thecloth in a position transverse to the axis of the needle 3 as the clothvis drawn toward the needle hy the l'eed roller 32, the presser' foot tlat 79 also assisting the workcarrier in this guiding ol' the clothtransversely, hy pressing the cloth down upon the cloth roller 1S, allas may he most clearly seen at Fig. lt); the ahove named elements thusconstituting means for guiding said cloth transversely to the axis ofand towards said needle.

To change the rapidity oll the feed, the length ol' the partialrotations of the feed roller 32 is changed hy adjusting the screw handle3S along the slot 3U. The handle 3S moves the har 5&4 and slides thefulcrum 33 along the lever 31, thus varying the length of the activeportions of the lever 3l and correspondingly varying the amount ofmotion communicated to the link 43. Adjustment may be made so that thefulcrum 33 is close up to the link 43, and with the fulcrum 33 in thisposition there is virtually no feed, so

that several stitches may be taken in the same place at the beginning orend of a seam to fasten the ends of the thread.
